Going through the same thing right now. I say forged my machinist says hyper. He said that since my car is mostly street that I should stick with the hyper pistons to avoid skirt failure on the forged ones. He did concur that the forged would be better in a mostly race app, but that does not apply to me. I also plan to spray a little (100 shot) and he said the hypers would be fine. I have been doing this for 10 years, him 35......so I dunno.
